## What are the rules for writing large numbers?

In primary school, children are typically introduced to basic rules for writing big numbers to help them understand and articulate numerical values.

Here are some simplified rules:

• Understanding place value: children learn that the position of a digit in a number represents its value. For example, in the number 536, the 5 represents 500 (hundreds place), the 3 represents 30 (tens place), and the 6 represents 6 (ones place).
• Using commas for thousands: they learn to use commas to separate groups of three digits in larger numbers for easier reading. For example, 3,456 or 10,987.
• Counting by hundreds, thousands, and millions: they practice counting in increments of hundreds, thousands, and eventually millions to grasp the concept of larger quantities.
• Reading and writing numbers in words: children are taught to read and write numbers in words, starting with smaller numbers and gradually progressing to bigger ones. For example, 456 can be written as four hundred fifty-six.
• Understanding orders of magnitude: they learn about the magnitude of numbers, understanding that numbers increase by factors of ten as they move to the left in the place value chart (e.g., units, tens, hundreds, thousands, etc.).
• Using number lines: number lines are often used as visual aids to help children understand the relative size and position of numbers on a scale.
• Visual representations: base-10 blocks or place value charts are used to help children visualise and understand the composition of larger numbers.

## How will this worksheet help my child with large numbers?

In this Read, write and order seven-digit numbers worksheet, your child is provided with a clear example of place value and how to write out a seven-digit number. They will then have plenty of opportunity to practise writing seven-digit numbers and understanding place value.

They will need to fill all the gaps in by writing the words in numbers or digits (depending on what is missing). Then, with help if needed, they can cut the numbers out and put them in order, from smallest to largest.
